Chill the seafood; I put it right from the shopping bag into the fridge.
More crab is great (at $1.50 a pop) if budget allows.

Add a tsp. of salt to 3 quarts of water and bring to a rapid boil. Throw in
the macaroni and turn down the heat so it doesn't bubble over. Cook 8 min
until tender, stirring occasionally. Avoid overcooking so it won't stick
together. Drain thoroughly in a colander and chill in the fridge. When
it's, like, cool, dump the macaroni into a big bowl.

Chop the celery and onion and add it. Drain the seafood and add. Put in two
good dollops of mayonnaise, but don't overdo it. Salt and pepper to taste.

Mix is all up and keep in the fridge till dinnertime. Serve with lettuce
and wedges of tomato. You can dust the top of the salad with a little
paprika.
